DISPENSING CLOSURE FOR BOTTLES Frahcz s E. i'ow'ie Jr,

Patented July 21, 1936 UNITED STATES PATENT OFFICE DISPENSING CLOS RECEPTACLE S,

URE FOR BOTTLES,

AND THE LIKE 2 Claims.

The invention relates to a drop closure for liquid bottles in which a predetermined quantity is discharged at each operation.

The purpose of the invention is on the one hand to provide a dispensing cap for bottles containing liquid, and on the other hand a cap that will prevent leakage of the bottle contents should the bottle be accidently upset.

With these and other purposes in view, such as will hereinafter be made manifest, the invention consists, in general, of the structural characteristics, arrangements of parts and combination of elements illustrated in the accompanying drawing, described in the following specification and specifically pointed out in the appended claims:

In the drawing, wherein like characters of reference are used to identify like parts in the several views,

Figure 1 is a fragmentary sectional view of a I bottle equipped with the dispensing cap.

Figure 2 is a view of the same with the closure liner removed.

Figure 3; is a view of the cap. washer, closure liner and bottle.

Figure 4 is top view of the dispensing cap.

Figure 5 is a view of the cork washer.

Figure 6 is a view of the modified form of the invention.

Referring to the drawing in detail In indicates a bottle containing extract or the like IS. The neck I l of the bottle has a ring or raised portion l2 thereon and the skirt or lower edge of the cap rests against the portion I2 when secured on the bottle. The neck of the bottle is screw threaded at I 4 and these threads are adapted to cooperate with the screw threads l6 of the cap IS in securing the cap in place. It is to be understood that the cap I5 may be secured to the bottle neck H in any desired manner and the invention is not limited to a screw thread cap.

The cap I 5 has an inwardly extending flange I 1 which defines a pocket'or depression on the inner surface of cap top. In the middle of the cap, which is substantially the middle of the pocket, is an opening I 8 extending through the cap. The pocket or depression is of a given size so that the quantity of liquid to be dispensed can be predetermined. The opening I 8 has a small flange or lip I9 extending outwardly from the top of the cap.

A washer 20 made of cork or the like is placed in the cap 15. The washer 20 has an opening therein of substantially the size of the pocket.

To insure the contents of the bottle against leakage in shipping a washer 2| is placed in the cap l5. When the contents of the bottle is to be used the washer 2| is removed and the cap containing the cork washer 20 is secured on the bottle. To discharge a given quantity of the extract the bottle is turned so that the extract fills the pocket and then the bottle is given a dash or shake. This operation causes a drop of a given size to be discharged at each shake of the bottle.

If the bottle after the liner 2| has been removed should accidentally be upset the extract will not have a tendency to leak out.

In Figure 6 is shown a modified form of the invention in which the liner or washer 2| is not removed but a hole 22 is made in the liner of approximately the size of the hole l8. The user of the liquid can by the use of a pin or needle puncture the liner 2| or the liner may be inserted with a hole already therein and. addition liner may be used whichmay be removed before the liquid is to be used. Due to the different viscosities of various liquids, the size of the drop can be regulated by increasing or decreasing the size of the hole in the cap and/or the liner; also the size of the hole and the thickness of the cork washer.

The combination of the pocket of a given size, the opening extending from the pocket, and the lip around the outer edge of the opening provides an efiicient drop dispensing cap and at the same time insures that the bottle contents will not tend to leak out should the bottle fall over.

It is to be understood that the illustrated form of this invention is merely the preferred form and that many difi'erent modifications in the details of construction may be made without departure from the spirit of the invention. Such modifications will readily suggest themselves to those skilled in the art and are to be understood as contemplated as a part of the invention insofar as they fall within the scope of the following claims.

I claim:

1. In combination with a container of the class described, a substantially fiat top closure cap, an inwardly extending flange in the top of said cap, a relatively small opening in the cap within the area defined by the flange, a washer in said cap and in contact with the inner surface of the top, a liner in the cap and positioned against the washer, and a relatively small opening in the liner extending into the pocket between the washer and the top.

2. In combination with a container of the class described, a flattop closure cap, a small pocket formed in the top of said cap, a relatively small dispensing opening in the top and located in the area defined by the pocket, a washer located in the cap and provided with a larger opening than the size of the pocket, 9. flexible liner in said cap and in contact with the washer, and a relatively small opening in said liner.
